VERTICAL BALING PRESS Filed June 7, 1949 5 Sheets-Sheet 2 Patented Oct. 6, 1953 UNITED STATES PATEN VERTICAL BALING PRESS Einar ulius J akob J onsson, Stockholm, Sweden Application June '7, 1949, Serial No. 97,639 g In Sweden Septe 1 Claim. (01. 100228) V g beam of a yoke-shaped support, the opening of said container being capable of being uncovered for permitting access to the interior of the container by moving the yoke and press piston rearward when the latter has been raised above the opening of the container.

The vertical baling presses hitherto employed sufier from the disadvantage that, when the press piston is raised above the container to enable the latter to be charged with material to be baled, the cross-beam of the support or yoke and the press piston cannot be moved into such a position that the opening of the container will be completely uncovered. This involves the disadvantage that the container cannot be charged directly from above and from any substantial height, and further that it will not be possible for a person conveniently to enter into the container when required during the course of the charging in order to stamp down the loosely accumulated material. For that reason it has most often been necessary to undertake this stamping operation which is repeatedly required when the charging is taking place, by means of the press piston proper, a procedure which is very tedious as compared with the first-mentioned one and which, in addition, involves an increased rate of wear of the mechanical equipment per production unit.

With a view to overcome the said disadvantages, according tothe present invention, there is proposed an improvement in such baling presses which makes it possible, when the piston is raised above the container, to move the piston into a position in which said opening is substantially completely uncovered for access to the container. For this purpose, a baling press according to this invention is mainly characterized by the features that said yoke carrying said press piston is pivotally connected to its support, and that said press piston, in addition to its being reciprocable in the direction of operation, is arranged to be displaceable relative to the crossbeam of said yoke in a direction normal to the plane of the yoke, whereby the opening of the container can be completely uncovered, in that said piston is displaceable relative to the foot mber 10, 1946 ends of said piston rods to such an extent that said footeends will be situated at or near one i piston proper instead of atparallel to said of the edges of said the central line of the piston edge, which is normally the case.

One embodiment of the baling press according to the invention is to be described in, the following by way of example, reference being had tofl' the accompanying drawings in which: 1

Fig. 1 is a frontal elevation view of a baling press incorporating the invention, the'press piston 1 being shown moved into the opening of the press container.

Fig. 2 is a left-hand side elevation view of the same baling press, the yoke being shown rocked rearward and the press piston displaced rearward into a position in which the opening of the 1,

press container is completely uncovered.

Fig. 3 is a partial end view showing in greater detail means for operating the shaft for movement of the baling press.

Fig. 4 is a partial sectional view through a piston rod showing in detail operating means therefor.

Fig. 5 is a plan view illustrating the guiding track, and

Fig. 6 is a partial side view showing thefguiding track and shoe arrangement.

Referring to the drawing the container of the baling press wherein the material in question is to be baled is designated with the numeral I. In this instance,'the container I is in the form of an upwardly open prismatic wooden box the front wall of which consists of a door la hinged at II to one side-wall of the container I, which door can be opened for the removal of a bale packed within the container, the door being adapted to be secured in its closed condition by means of latches l8. The container l is supported on a solid base 2 or on a floor, and below the container l a transversely extending pivot rod 8 is mounted in said base 2 centrally below the side-walls so as to project from the outer surfaces thereof. Journalled on the end portions of the pivot rod 8 are the lower ends of the legs 5 of a yoke-shaped piston supporting member or yoke 4, said legs 5 being thus adapted, when the yoke is being rocked, to move in parallel relation to the sidewalls of the container. The intermediate portion of the yoke 4 is formed by a cross-beam 6 which serves as a carrying and guiding member for the piston rods 1 of the press piston 3 and also carries the driving equipment (to be described hereinbelow) for vertically reciprocating the press piston T. om n.

The press piston 3 is formed by a robust and relatively heavy plate which, when moved into the container 1, fits with its edge surfaces rather closely in the interior of the container 1. The press piston 3 is mounted on a pair of piston rods I which are vertically reciprocable through vertical bores in the cross-beam 6. In the actual embodiment, the piston rods 1 are formed partly as racks, theflteethol b ofawhichzareeengaged aby toothed gears .13 keyed toe-a horizontalishaftfifl, the shaft I! being rotatably mounted in the cross-beam 6 and adapted to be rotated by means a of any suitable power source.
